What I did in a two-switch one-bulb situation was:
- Keep the dumb bulb.
- In the first wall switch hole put a ZigBee switch that can activate using the pushbutton switch I have on the wall.
- In the second wall switch hole, I left the circuit permanently closed, disconnected the switch, and put that switch on a Philips Hue module.
A bit of automation makes the Philips Hue module toggle the relay in the first wall switch hole. Same functionality as before, no issues.
